The thermometer is easy to use and has a high measuring accuracy. It beeps 4 x once it has measured no change in temperature for a certain time; it is recommended jeoch (within the cycle of observation just) on / to increase the span of 3 minutes (the value can then by a few hundredths of a degree change up because it is a maximum thermometer). There you will find detailed information for rectal, oral and axillary measurement method as well as for disinfection in the instructions.
Plus points: easy handling, very good manual, water resistance, Table for recording the values (both temperature and cervical mucus)
Drawback for some: manual only in English The measurement accuracy that is specified on the package, is +/- 0.05 ° C, while in the Bedienugsanleitung of +/- 0.1 ° C is mentioned (if I remember correctly).
On the whole, I can only recommend this thermometer!
